Cannot see walls/floor/sky

[Zelius]

Hello all,

I copy/paste the new files into my existing titanium client, load up, and can't see walls/floors etc. I see others have had similar issues and tried to just copy/paste over the individual contents of the MPL/SPL folders rather than the whole folder, however this hasn't changed anything. I really don't have any clue how to fix this at this point. I've attempted re-installs as well. Any advice would be awesome, thanks.
